I can't remember exactly but I didn't get called up to MLB until I got invited to Spring Training after my first year which I thought was cool because after playing prior years I used to tear through AA (and AAA when needed) and be in the Majors in time to make the MLB All-Star Game and from a presentation standout point and content creating standpoint I'd like to stick around the minors longer... I'm still lowkey hoping that Single A is made playable in next years game seeing as you would just have to add 300 more player slots and I'd imagine it shouldn't be that difficult on PS5 and probably should've been done on PS4 especially considering the amount of free agents and legends in the game... I really hope they are able to expand these rosters for that to happen at some point... and then maybe do something where you select where you start in the organization... but make it so you have to choose wisely because if for example you are a 60 overall and you choose to be on the MLB team it could mean that you are buried on the bench to start off with sporadic playing time (pinch hitting, pinch running, defensive substitution) depending on your attributes.
